ETHICS IN MATHEMATICS: A BRIEF HISTORY OF MATHEMATICAL PROOFS
1.0 Introduction
Our Public Affairs Mission at Missouri State University emphasizes three important
traits: cultural competence, community engagement, and ethical leadership. onsidering my
intentions to obtain a doctorate in mathematics and to teach college mathematics, ! must e"hibit
ethical leadership in my position. omposing this documented research report on ethics in
mathematics has shed much light on invaluable information that #ill undoubtedly inform my
future employment. ertainly, it #ould surprise no one to assert the value of an ethical system of
communicating mathematical results$ in fact, e"amining ethics in mathematics underscores the
necessity of viable mathematical results in sciences other than mathematics itself, such as
physics, chemistry, architecture, and more. Overall, ! claim t#o things above all else: that proofs
in mathematics have undergone consistent changes over the course of the last t#o millennia and
that proofs in mathematics are by nature ob%ective truths. &"amining the history of mathematical
proofs, ! #ill give pertinent historical information and anecdotes$ ! #ill supply relevant
definitions and terminology$ and ! #ill detail a brief introduction to mathematical logic. On the
#hole, therefore, ! intend #ith this documented research report to present my findings on the
ethical nature of mathematical proofs by e"amining the history of proof techni'ues.

Pythagorean heorem states that the sum of the s'uares of the legs of a right triangle x and y
e'uals the s'uare of the hypotenuse z / or x0 1 y0 2 z 0. Using this, a Pythagorean triple is three
positive integers a, b, and c such that a0 1 b0 2 c0. On first glance, it is incredible that the
)abylonians #ere able to solve an e'uation in three variables through such elementary means,
but a deeper loo( reveals the most spectacular aspect of the )abylonian3s discoveries: they did
this before the Pythagorean heorem #as ever even con%ectured, let alone proven *++.
-ather, it #as not until one thousand years later that Pythagoras and his follo#ers / the
Pythagoreans / established and proved their theorem on right triangles. )efore the time of
Pythagoras, mathematics #as conducted intuitively: if the result of a claim seemed to hold in
general, the claim #as thought to be true *4rantz 56. One of the first radical thin(ers in
mathematics, Pythagoras rebu(ed this norm, believing instead that the mathematical sciences
need be founded in strong, ob%ective reasoning, and, further, asserting that many geometrical
results of the time could be deduced from a small list of postulates that #ere ta(en #ithout
'uestion to be true *56. !n this #ay, &uclid #ould dra# the necessary inspiration to generate the
mathematical #orld3s first attempt at a complete a"iomatization of all geometry.
&uclid the 7eometer emerged from the melting pot of ideas of his predecessor Pythagoras
t#o hundred years later, and he #ould go on to release #ith his Elements #hat remains one of
the most essential #or(s in mathematics. &uclid3s most notable efforts sought a connection
bet#een mathematics and logic in a rigorous manner, asserting that proofs follo# from
definitions and a"ioms that are ta(en as fact #ithout further 'uestion *58. 4rantz points out that
&uclid began #ith a fe# undefined terms that #ere commonly accepted #ithout %ustification and
used these to formulate his self9evident a"ioms, #ith #hich he introduced his logical e"position
in a very sophisticated and almost modern manner *5+. Of course, &uclid3s famed fifth postulate

/ #hich states that there is a uni'ue line parallel to any given line / has for the last t#o thousand
years caused debates concerning the soundness and independence of his a"iom and, in this #ay,
has e"posed the #ea(nesses in the logic of the ancients.
2.1.2. Closing the Logical Gaps
&uclid3s Elements remains among the most astounding mathematical #or(s to resonate
through the halls of time, but even this master#or( of ancient 7reece has been sho#n / by our
contemporary standards / to contain several fla#s in logic. ommenting on this and other
mathematical follies, ieudonn; contests that the ma%ority of insufficient or erroneous proofs
throughout history have resulted from a lac( of focus on the underlying mechanics of proof
*ieudonn; 06+. )efore #e e"amine this claim, let us recall the structure of a deductive proof.
Proofs in mathematics are logical se'uences of con%ectures made from an initial
assumption / or several assumptions / and ending #ith a conclusion *06+. &ach step in a proof
should follo# directly from either our initial assumption or some (no#n a"iom or theorem.
Previous results have been sometimes invalidated by more recent commentators, ieudonn;
says, due to some confusion regarding the initial premise and a similar premise from #hich a
conclusion is dra#n #hen in fact it is the conclusion analogous to the similar premise that
follo#s *06+. Other instances sho# that, as ieudonn; observes, some proofs have employed
inferences and reasonable assumptions that had not yet been proven, resulting in falsity *06+.

or a conclusion dra#n from previous steps. ?e define rigor as soundness and ob%ectivity of an
argument, guaranteed by strict implementation of and obedience to a"ioms and definitions.
4itcher argues that although some mathematical (no#ledge seems self9evident, it
remains necessary to prove these apparent truths in a rigorous #ay so as to ma(e our
understanding more taut and ob%ective *+@6. 4itcher asserts that as the study of mathematics
progresses, our notion of rigor li(e#ise progresses, so eventually, things that #e consider to be
rigorous at present #ill come to be considered unrigorous *+@6.

auchy, )olzano, and ?eierstrass #ere among the pioneers of the ne#ly9invented branch of
mathematics called analysis *oel 58+. auchy and the li(e realized the misleading nature of
geometry and gre# #ary of its grasp on several fields in mathematics, according to oel, and as
such, they sought to a"iomatize calculus using a more algebraic argument *588, 58+. Similarly,
Saul attests the crucial role of simple arithmetic / as opposed to the early geometric and intuitive
methods / in auchy and )olzano3s development of mathematical rigor *Saul ii. onvincingly,
Saul argues that ine'ualities #ere the fundamental tools by #hich the nineteenth century analysts
achieved their goal of precision, noting that until the time ine'ualities #ere studied and
developed in9depth by auchy, rigorous proofs of calculus #ere not often supplied *0+, 0J.
learly, auchy played an invaluable part in the development of mathematical proofs and
in the establishment of a ne# standard of rigor in mathematics. auchy is credited #ith
converting many of his contemporaries to forego the usual and mechanical computations and
casual intuition on #hich mathematics #as founded at the time in favor of a universal
mathematical language based on the ob%ectivity of a"ioms and definitions *&ves +>. &ves
portrays auchy3s body of #or( as prolific, as #ell as detailed and formal *+. ontemporaries
of auchy, on the other hand, did not all praise him #ith such esteem as &ves does$ in fact,
Schubring establishes a more realistic vie# of auchy, lending authenticity to the
mathematician3s body of #or( by establishing important criticisms that demonstrate #hy auchy
has become so important and highly regarded today *Schubring +80, +88.
&ven though auchy and his contemporaries had successfully established the discrepancy
bet#een geometry and algebra / developing a highly sophisticated and formal system of
a"iomatic proofs using arithmetic / there #as still much #or( to be done as history moved
to#ard the middle of the nineteenth century. Particularly, our notion of real numbers #ould begin

Other curious geometric parado"es reveal themselves a bit more easily than Neno3s.
Picture any straight line that e"tends itself indefinitely in both directions. ?e #ill stipulate that
our line does not inherently possess any breadth and, further, that this line in particular does not
inherently pass through any points. Picture also a semicircle of finite length laid do#n ne"t to
this line. ?e re'uire that our circle / li(e our line / must not inherently pass through any points.

sho# that a semicircle of finite length possesses the same number of points as a line of infinite

segments of different lengths that someho# / contrarily / possess the same number of points.

Under the long9standing misinterpretation of the properties of infinity, even the
characteristics of certain infinite collections of numbers remained shrouded in doubt and
misunderstanding. Predating antor by nearly 866 years, the !talian physicist and astronomer
7alileo 7alilei first observed the similarities bet#een the cardinality / or size / of the set of
natural numbers and the set of s'uares of natural numbers. ?e define the natural numbers to be
positive, #hole numbers. )rilliantly, 7alilei observed that you can pair off a natural number and
its s'uare / for instance, *5, 5, *0, +, *8, >, and so on / such that it appears as though there are
the same number of ob%ects that are s'uares of natural numbers as there are natural numbers *.
?e refer to this pairing as a bi%ection because every natural number refers to a uni'ue s'uare /
and so no t#o natural numbers refer to the same s'uare / and every s'uare is uni'uely
determined by a natural number, hence no s'uare is absent from our list. antor #ould later
prove that the set of natural numbers and the set of s'uares of natural numbers possess the same
cardinality$ that is, parado"ically, there are %ust as many s'uares of natural numbers as there are
natural numbers, even though the s'uares are more spread out.

same cardinality as the set in #hich it is contained is the e"act property that distinguishes infinite
sets from finite sets, as ede(ind theorized in 5@ *J=. Using this characterization, it is clear
that the set of natural numbers is infinite since at least one of its proper subsets / namely, the set
of s'uares of natural numbers / possesses the same size. antor demonstrated that the cardinality
of the natural numbers is the smallest infinite cardinality. &ven the set of rational numbers
possesses the same cardinality as the set of natural numbers. ?ith this astonishing brea(through,
he deemed this cardinality the first transfinite number Q6 , #hich is the Debre# numeral Kaleph
nullL *J=.
Ultimately, ho#ever, antor3s development of set theory proved itself to be parado"ical,
revealing the problematic nature of intuition and even further underscoring the misunderstanding
of the enigma of infinity. antor3s eponymous parado" characterizes many other ostensibly
contradictory results from the li(es of esare )urali9Borti and )ertrand -ussell *=5. onsider
the collection of all cardinal numbers / namely, the set of all infinite cardinalities. )ecause there
is no largest cardinal number, this collection is itself infinite, and in fact, the cardinality of this
collection is even larger than any of the cardinalities contained.
2.$.$. -ronecer’s Criticism
onsidering the breadth of abstraction and intricate nature of his arguments, antor3s
convoluted discoveries #ould come under heavy criticism from finitists the li(es of 4ronec(er.
&ven as early as 5@@, 4ronec(er attempted to bloc( several of antor3s publications in Crelle’s
/ournal / a famed 7erman mathematical periodical / due to a fundamental difference in
ideology: among many other of his be#ildering opinions, 4ronec(er believed neither in the
e"istence of infinity nor in the e"istence of irrational and transcendental numbers *O3onnor 8.

-elations bet#een antor and 4ronec(er never bettered, and #hen 4ronec(er passed in 5>5,
the mathematicians remained at odds, never to settle their dispute. antor, ho#ever, continued to
e"tend #arm regards and #holehearted respect to his colleague until his untimely passing *+.
&thics in mathematics may not be better demonstrated else#here than in 4ronec(er and
antor3s infamous bic(ering. antor3s formalism / or a"iomatic mathematics based on abstract
manipulation of inherently meaningless symbols / represents a po#erful tool that
mathematicians use to overcome and understand the counterintuitive and e"tremely subtle nature
of certain mathematics, and it aids the discovery of important results such as set theory. On the
other hand, 4ronec(er3s intuitionism / or sub%ective mathematics that re%ects the notion and
importance of a"iomatic systems / e"emplifies a more practical aspect, restricting the
mathematician3s #or(9space to the tangible and constructible.

thoroughly enough by auchy and his contemporaries *-ec( +. )y relating the studies of
calculus and arithmetic even more closely than his predecessors, 7erman mathematician -ichard
ede(ind too( it upon himself to rid analysis of its intuitive foundations entirely *+.
Oddly enough, ede(ind began his arithmetization of calculus by establishing his theory
of ede(ind cuts, #hich directly related the real number system #ith a geometric line *-ec( +.
?ith his eponymous Kcuts,L ede(ind observed the similarities bet#een the set of rational
numbers / or the set of fractions / and a tangible, straight line$ ho#ever, it became apparent after
some consideration that rational numbers cannot be e"pressed on a continuous, gap9free line,
since there are numbers on a continuous line that cannot be e"pressed as fractions / the s'uare
root of t#o, for e"ample *+. &"panding this idea further, ede(ind succeeded in e"pressing the
real number system in a completely original manner, finally relating rational and irrational
numbers and demonstrating that / using his system / proofs could then be obtained about the
real numbers that had not been possible before *J. &ssentially, ede(ind had discovered the
missing lin( bet#een geometry, algebra, and calculus, effectively freeing mathematics from its
intuitive upstart and advancing the systematization and rigorization of analysis.

before passing on to the ne"tL *&ves =8J. One of Dilbert3s various accomplishments included
his #or( to#ard the a"iomatization and systematization of all of mathematics / on #hich he
#or(ed alongside )ernays / called proof theory$ in 5>85, ho#ever, 7del demonstrated that
Dilbert3s efforts #ere in vain #hen he proved in KunimpeachableL style that Dilbert3s proof
theory could not hold in every field of mathematics *&ves =8+98J.
Oga#a nevertheless emphasizes Dilbert3s development of deductive rigor and his belief
in the freedom of concept9formation as a means to systematize mathematics and to establish the
preeminence of mathematics as universal and ob%ective truth that does not rely on any
epistemological assumptions *Oga#a 0, 56. One immediate conse'uence of Dilbert3s ubi'uity is
his a"iomatization of geometry, ta(ing nearly t#o9thousand9year9old notions of &uclid and
reinvigorating them #ith more sophisticated, modern foundations. !mportantly, this
establishment preceded some of the most groundbrea(ing results in physics, such as &instein3s
theory of relativity *&ves =8J. Overall, Dilbert3s grand efforts / more than anyone in history /
propelled mathematics to#ard the ultimate goal of rigor and consistency, and as such, he remains
one of the most rightfully celebrated mathematicians of all time.

&ven more than his revolutionary and deeply impactful successes, oddly enough,
Dilbert3s ultimate failure to establish a set of a"ioms that could provide a foundation for all of
mathematics remains one of the most important shortcomings in scientific history, simply
because it resulted in the invaluable and indelible !ncompleteness heorems: t#o elegant results

7erman logician / demonstrated in 5>85 #ith his Birst !ncompleteness heorem that there e"ist
arithmetic statements that are neither provable nor refutable in the a"iomatic system of Peano
arithmetic. ?ith his Second !ncompleteness heorem, 7del demonstrated that there are indeed
mathematical truths that cannot be harvested using the classical a"iomatic methods that had been
in development since the time of &uclid. ombining both of these conclusions, Dilbert3s program
/ #hich in essence aimed to establish the provability of every statement that could be
constructed in Peano arithmetic / #as rendered unrealizable *agel et al. =.
reative and elo'uent in his arguments, 7del challenged the ostensibly limitless
potential of the a"iomatic methods in a manner that no mathematician or logician had before.
Using conventional notation and meta9mathematics, 7del #as able to manipulate the calculus
of logic / or the formalized logical system consisting only of inherently meaningless mar(s and
strings of mar(s called formulas / in such a #ay as to derive a )erry parado" in the synta" of
meta9mathematics *0. Put simply, 7del #as able to ingeniously combine empty mathematical
symbols and #ords into a meta9mathematical statement that, #hen interpreted, inherently
contradicted itself. One e"ample of a simple )erry parado" follo#s.
6Behold the smallest positi)e integer not expressible in &e!er than thirteen !ords78
learly, the sentence contains fe#er than thirteen #ords / namely, it contains t#elve #ords / but
even more, these t#elve #ords characterize the very nature of the ob%ect that the statement
claims cannot be e"pressed$ in fact, the statement itself is the e"act definition of the integer that
it claims it cannot itself define. Dence, the statement lies in self9contradiction.

Perhaps it is unsurprising to consider the amount of cunning and imagination involved in
the aforementioned argument$ ho#ever, all too fre'uently, mathematics is misunderstood as
blind, formal manipulation that lac(s e"pression. losely e"amined, 7del3s proof reveals the
often9overloo(ed artistic and linguistic aspects of mathematical proofs and, as such,
demonstrates the intrinsic limitations of philosophical arguments devoid of intuition.
2.5.2. +he 'nherent 9eanesses o& the :xiomatic 4ethod
Of course, 7del3s argument #as far more convoluted and comple" than demonstrated
above: as mentioned before, there is a noticeable air of narrative license and artistic liberty in the
!ncompleteness heorems. Upon publication, in fact, 7del3s results remained so enigmatic and
complicated that they #ere incomprehensible even to many mathematicians *8. ontrarily,
7del3s arguments #ere astonishingly rooted in simple arithmetic involving the prime
factorization property of the integers and simple sentential variables / or letters that stand in
pro"y for logical statements / in the calculus of logic, concatenated #ith the logical connectives
such as Knot,L Kor,L and Kif V thenL as #ell as useful punctuation mar(s.
onstituting the cru" of 7del3s proof are his eponymous 7del numbers. ?e assign the
first ten 7del numbers / 5, 0, 8, V, >, and 56 / to the elementary signs of our calculus %ust as

out that the statement defined by this 7del number is, K6 2 6L *@=. )y applying these t#o
simple results to the set of all statements generated using the elementary signs #ithin the
calculus, 7del demonstrated that every statement about the calculus can be e"pressed as a
7del number #ithin the calculus and, therefore, that a )erry parado" is obtainable *@@.
areful and intentional in his reasoning, 7del e"posed the inherent #ea(nesses in the

Of any development in history, the tireless efforts of mathematicians as far bac( as 866
) to establish a threshold of mathematical rigor mar( easily one of the greatest / and most
essential / human con'uests ever endeavored.
Undoubtedly, #e need rigor to create a foundation of certainty and ob%ectivity in the
physical sciences. -igor in mathematics ensures that our intuitive reasoning is ob%ectively
founded. -igor enables us to say #ith certainty / barring human error / that our hypothesized,
testable results #ill hold universally / and every time / if an e"periment is conducted under the
same parameters. -igor rules out the possibility of #ild variation and chaos.
-igor is our only defense against the inevitable entropy of the Universe.

Overall, based on my research, ! find it apparent that our current system of mathematical
rigor is pristine, according to current standards. onsidering every aspect of this documented
research report, ! believe firmly that our current logical foundations allo# for the most efficient
and ob%ectively true reasoning in mathematics and science.
ommenting on the Brench mathematician Pierre uhem, Ioseph Iesseph observes and
empathizes #ith uhem3s assertion that the history of mathematics has been a long, additive
process in #hich past results are built upon but not challenged *Iesseph ++>. ontrary to
uhem3s philosophy, ho#ever, Iesseph admits a fla# in uhem3s conception that mathematical
rigor has been unchanging since the time of the 7ree(s and )abylonians. -ather, Iesseph asserts
that the la#s of logic have been 'uestioned time and again by more recent commentators and that

the arguments such critics have made have been metaphysical in nature *+J6. &ven more,
Iesseph states very clearly that he believes that no measure of mathematical rigor e"isted up to
and including the time of the mid9eighteenth century, and he further suggests that the
mathematical community give up on the idea of an immutable, unchanging standard of
mathematical rigor in favor of a more fluid foundation *+J0, +J8.
?hile ! support Iesseph3s interpretation and understanding of mathematical rigor and
confirm his observations on the history of mathematical rigor, ! must disagree #ith his
pessimistic vie# of the potential of mathematical proofs. Unrelentingly, ! remain most optimistic
in hope that the future #ill continue to unravel further the mysteries of current mathematical
conundrums and, thus, #ill gro# upon the present strength of the system.
